Chemically-induced wing deformities?

I am interested in rendering D. melanogaster incapable of flight and would
like to do so by inducing wing deformities similar to those seen in the
vestigial and apterous mutant strains. If possible, I would like to expose
eggs, larvae, or pupae to some chemical treatment that would retard wing
development while producing otherwise normal adults. Is this possible? If
not, is there another treatment that would produce the desired effect?
I would greatly appreciate any information and/or suggestions that might be
provided. Thanks in advance.
